Does the 550 & 700 Grizzly have as many fuel injector issues as Polaris does . It seems that allot of POPO's have issues and if Polaris ever stops making the 500 carb I'll be looking at a Grizzly but I don't want to be in the same boat as them . I'm running a 08 500 carb POPO with 7000 miles problem free it's been a fantastic machine but a 500 EFI scares the hell out of me . Would I get 7000 miles problem free from a new 550 or 700 Yamaha like I don't want to see any codes on my dash .
